NodeJs app runs fine locally - but dumps when deployed to Edge

Google Cloud Apigee

This code here is a simple web server to host my html application. Runs perfect on my local host.

var express = require('express');
var app = express();

var oneDay = 86400000;

app.use(express.compress());

app.use(express.static(__dirname + '/public', {
    maxAge: oneDay
}));

app.listen(process.env.PORT || 3000);

Deploys on Edge. But errors out when called.

Hi @tetadmin, the express compress module depends on an undocumented _implicitHeader function that the Trireme does not implement. More details (and a workaround) here: https://github.com/apigee/trireme/issues/124

If you are running in the Apigee cloud then this will be fixed soon. In the meantime, you can try the “monkey-patch” referenced by Dibyo, which should get you going.
